​
Success Metrics & KPIs

​
Phase 1 Metrics

  • ✅ All core APIs functional
  • ✅ TypeScript compilation without errors
  • ✅ Database schema properly defined
  • ⏳ All endpoints return correct data types
  • ⏳ Response times < 100ms for list operations

​
Phase 2 Metrics (Multi-Language)

  • ⏳ Language detection working for all methods
  • ⏳ JSONB migration completed without data loss
  • ⏳ All existing data properly migrated
  • ⏳ API responses correctly localized
  • ⏳ Database constraints enforcing English translations
  • ⏳ GIN indexes created and performant (< 50ms queries)

​
Dependencies & Risks

​
Critical Path Items

Phase 2 Database Migration - CRITICAL
  • Must complete by 2026-01-20
  • Risk: Database data integrity
  • Mitigation: Backup before migration, test locally, rollback plan available

​
High Priority Risks

Impact: High - Data loss, service downtime Probability: Low (with proper testing) Mitigation: Backup before migration, test locally, rollback plan Status: Monitoring
Impact: Medium - Incorrect localization Probability: Low (well-defined spec) Mitigation: Comprehensive API testing Status: Preventive measures in place
Impact: Medium - Slow API responses Probability: Low (with GIN indexes) Mitigation: GIN indexes, expression indexes, query optimization Status: Monitoring
